Definitions
- the embodiments herein relate generally to a new surface raised above an existing surface.
- stage floors were challenging to assemble, align and adjust because of a mistaken theory of nodal assembly that plagues the prior art.
- Nodal assembly is the theory that a stage floor consists of stringers arranged in rows, columns and, in some cases, diagonals that intersect at nodes where either all the stringers terminate or all the stringers in a single direction terminate.
- the prior art includes: U.S. Pat. No. 5,983,582 issued to Vugrek; U.S. Pat. No. 8,162,569 issued to Kennedy; U.S. Pat. No. 6,336,296 issued to Ishibashi; U.S. Pat. No. 4,277,923 issued to Irish; European Patent Application 0529073 filed by Haka; U.S.
- Patent Application Publication 2010/0089229 filed by Ackerman U.S. Pat. No. 4,085,557 filed by Tharp; U.S. Pat. No. 7,546,715 issued to Roen; U.S. Pat. No. 6,106,186 issued to Jines; U.S. Pat. No. 4,922,670 issued to Naka; U.S. Pat. No. 3,318,057 issued to Norsworthy; U.S. Pat. No. 8,156,696 issued to Hubbard; U.S. Pat. No. 8,181,399 issued to Knight; U.S. Pat. No. 8,387,317 issued to Kugler; and U.S. Pat. No. 5,644,879 issued to Barr.
- Elevated building surfaces such as elevated floors, decks, terraces and walkways are desirable in many environments.
- Prior art decks, such as Irish, essentially rely on having elongated members terminate at each node. This construction leads to a substantial time sink in assembly, and a low strength to weight ratio.
- the present invention solves this problem.
- Both Ackerman and Kennedy teach a bulkhead for a safe room that utilizes a series of nodes that are bolted to a number of elongated members as a cross bar that runs indefinitely along a wall. If such a construction would be applied to a floor there would be no modular theory of assembly resulting in a substantial time to assemble, further, there would be substantial deflection in the deck when compared to embodiments of the present invention.
- Roen tries to combine the teaching of the continuous rails in Ackerman and Kennedy with the floor teaching of Vugrek, Norsworthy an Ishibashi, and concludes that the best way to do this does so by having a plurality of parallel members resting on top of a plurality of perpendicular members. While this enables a key system as in Naka, Jines and Kugler for sliding floor panels, those panels are still only supported by the keys in the upper member and would deflect under moderate loading.
- Hubbard teaches a floor system that involves a series of continuous parallel members that cross many nodes separated by a series of perpendicular members that terminate at each node. Rather than utilizing an anchor for structural support, Hubbard teaches a central hub that is connected to a pneumatic shock absorber and then a series of struts and pads are adjacent to pedestals. It is specious as to whether this works and Hubbard offers no testing results. More likely, the arrangement of the perpendicular members renders the device likely to fail at those nodes away from the pedestals.
- a stage floor assembly can be easily assembled, aligned and adjusted even on an uneven surface.
- the stage floor assembly includes a plurality of pedestals with each pedestal further comprising a pedestal base attached to a plurality of rods.
- a plurality of deck plates is attached to the plurality of stringers creating a surface to absorb and distribute loads across pedestals preventing an unacceptable deflection across the stage floor assembly.
- the plurality of rods further comprises a plurality of threaded rods and a first plurality of unthreaded rods.
- the plurality of threaded rods can be mechanically coupled to a pedestal cover with threaded fasteners in order to keep the stage floor assembly at a consistent height.
- An angular support is mechanically coupled to a first unthreaded rod on a first pedestal and second unthreaded rod on a second pedestal in order to align the first pedestal to the second pedestal as well as to disperse loading from the first pedestal and the second pedestal.
- the angular support further defines a diagonal between the opposite corners of the basic floor subassembly square. This diagonal being fixed to the pedestals at the opposite corners rigidly constrains the subassembly ensuring the support grid subassembly remains square.
- the plurality of stringers are connected to the threaded rods.
- the pedestal cover is further mechanically coupled to a second plurality of unthreaded rods in order to match the first plurality of unthreaded rods to better secure the angular support.
- the stage floor assembly distributes loads from the pedestals to the plurality of stringers and the angular support to resist damage during exposure to loading from an explosive blast.
- the floor grid During exposure to explosive blast, the floor grid, with decking and pedestal cover plates installed, will react as a continuous membrane and will flex without separating into discrete components that could become missile hazards.
- This membrane action is enabled by the interconnected nature of the floor support grid where a continuous stringer crosses each pedestal and two similar stringers terminate at the same pedestal.
- This construction results in a support grid that is at once directly interconnected with a continuous stringer into each adjacent subassembly square.
- This construction will resist damage during exposure to explosive blast in a manner superior to previous floor designs consisting of discrete square floor subassemblies connected to each other by clips, threaded fasteners, or cam lock systems.
- a method of assembling a stage floor allows a user to assemble, align and adjust the stage floor.
- the method comprises the following steps, not necessarily in order: First a user places a first pedestal, a second pedestal, a third pedestal, and a fourth pedestal on ground in a location where a stage floor is desired. Next the user, connects the first pedestal and the fourth pedestal with a first stringer such that the first stringer passes through the fourth pedestal and terminates at the first pedestal. Then the user connects the first pedestal and the second pedestal with a second stringer such that the second stringer passes through the first pedestal and terminates at the second pedestal. After this the user connects the second pedestal and the third pedestal with a third stringer such that the third stringer passes through the second pedestal and terminates at the third pedestal.
- the user connects the third pedestal and the fourth pedestal with a fourth stringer such that the fourth stringer passes through the third pedestal and terminates at the fourth pedestal.
- a user can attach a deck plate to the first pedestal, the second pedestal, the third pedestal and the fourth pedestal.
- the user can attach an angular support to the first pedestal and the third pedestal. Depending on the height of the surface a user can adjust the pedestal height to ensure the deck plate is level.

- FIG. 11 demonstrates one way angular support 40 can be used to both align and distribute loads from pedestal 10 .
- FIG. 12 shows how top plate 60 can be utilized to cover pedestal 10 , but still allow access to pedestal 10 for adjustments. While stringers 30 are usually the same length some stringers 30 will terminate a few inches past the pedestal 10 , rather than extending outward a uniform length.
- FIG. 2 and FIG. 3 show pedestal 10 in more detail, pedestal foot 24 is mechanically coupled to threaded rod 14 . Threaded rod 14 is further mechanically coupled to rotation nut 22 . In some embodiments, pedestal foot 24 , threaded rod 14 and rotation nut 22 can be machined as a single unit or can be two or three units connected together, for example, by welding.
- Pedestal 10 further comprises pedestal base 12 mechanically coupled to threaded nut 16 .
- Threaded nut 16 is machined to be coupled to threaded rod 14 .
- a user can affix pedestal base 12 to threaded rod 14 by rotating threaded nut 16 around threaded rod 14 .
- Pedestal base 12 is further mechanically coupled to first threaded pedestal rod 18 A, second threaded pedestal rod 18 B, third threaded pedestal rod 18 C and fourth threaded pedestal rod 18 D. Threaded pedestal rods 18 can be used to align stringers 30 as shown in FIGS. 4 through 12 below.
- Pedestal base 12 is further mechanically coupled to first unthreaded pedestal rod 20 A, second unthreaded pedestal rod 20 B, third unthreaded pedestal rod 20 C and fourth unthreaded pedestal rod 20 D.

- Threaded pedestal rods 18 are bored with a threaded cavity that can accommodate threaded fasteners 64 .
- pedestal base 12 can be covered with pedestal cover 60 .
- Pedestal cover 60 is mechanically coupled to first unthreaded cover rod 68 A, second unthreaded cover rod 68 B, third unthreaded cover rod 68 C and fourth unthreaded cover rod 68 D.
- Unthreaded cover rods 68 can be used to accommodate angular supports 40 as shown in FIGS. 9 , 11 and 12 below.
- Pedestal cover 60 is perforated with first fastener hole 62 A, second fastener hole 62 B, third fastener hole 62 C, and fourth fastener hole 62 D.
- the fastener holes 62 are sufficiently large to accommodate a threaded fastener 64 .
- a user can mechanically couple pedestal cover 10 to threaded rods 18 in the following manner, a user can insert first threaded fastener 64 A through first fastener hole 62 A and into first threaded rod 18 A. Similarly, a user can insert second threaded fastener 64 A through second fastener hole 62 A and into second threaded rod 18 A. Likewise, a user can insert third threaded fastener 64 A through third fastener hole 62 A and into third threaded rod 18 A. Finally, a user can insert fourth threaded fastener 64 A through fourth fastener hole 62 A and into fourth threaded rod 18 A.
- the user can remove cover cap 70 covering central cover hole 66 giving the user access rotation nut 22 .
- pedestal plate 12 will not rotate, but pedestal foot 24 will rotate and will move proximate or distant pedestal plate 12 depending on the direction turned. This enables a user to perform pedestal height adjustments from a completed stage floor assembly and to ensure that a plurality of pedestals are at a consistent height.
- FIG. 4 to assembly the deck a user first places a plurality of pedestals 10 in a location roughly were nodes are planned to be. This does not need to be flat since embodiments of the present invention can easily accommodate an uneven surface.
- the pedestals are marked first pedestal 10 A, second pedestal 10 D, third pedestal 10 C and fourth pedestal 10 B. There is no need to measure to be exact, since the pedestals can be easily moved and stingers 30 , as noted below, are self-aligning.
- Stringer 30 is a support member with five perforations.
- Four perforations are sufficiently large to accommodate a threaded rod 18 .
- the fifth perforation is sufficiently large to accommodate rotation nut 22 .
- the first perforation is proximate a first end such that the distance from the perforation to the first end is approximately one half the distance from threaded rod 18 to rotation nut 22 .
- the second perforation is proximate a second end such that the distance from the perforation to the second end is approximately one half the distance from threaded rod 18 to rotation nut 22 .
- the third and fourth perforations are aligned to be a threaded rod diagonal distance apart.
- the threaded rod diagonal distance is equal to the distance between threaded rod 18 A and threaded rod 18 C or the distance between threaded rod 18 B and threaded rod 18 D.
- a user puts the first stringer hole onto first pedestal third threaded rod 18 C 1 on first pedestal 10 A.
- a user then places the third stringer hole and the fourth stringer hole onto second pedestal first threaded rod 18 A 2 and second pedestal third threaded rod 18 C 2 on second pedestal 10 D.
- a user next places second stringer 30 B perpendicular to first stringer 30 A on first pedestal 10 A such that the second stringer third hole fits over first pedestal fourth threaded rod 18 D 1 and the second stringer fourth hole fits over first pedestal second threaded rod 18 B 1 on first pedestal 10 A. Then the user places the second stringer fourth hole over fourth pedestal fourth threaded rod 18 D 4 on fourth pedestal 10 B.
- a user next places third stringer 30 C perpendicular to second stringer 30 B on second pedestal 10 D such that the third stringer third hole fits over fourth pedestal first threaded rod 18 A 4 and the third stringer fourth hole fits over fourth pedestal third threaded rod 18 C 4 on second pedestal 10 D. Then the user places the third stringer fourth hole over third pedestal first threaded rod 18 A 3 on third pedestal 10 C.
- a user next places fourth stringer 30 D perpendicular to third stringer 30 C on third pedestal 10 C such that the fourth stringer third hole fits over third pedestal second threaded rod 18 B 3 and the fourth stringer fourth hole fits over third pedestal fourth threaded rod 18 D 3 on third pedestal 10 C. Then the user places the fourth stringer fourth hole over fourth pedestal second threaded rod 18 B 2 on fourth pedestal 10 D.
- Angular support 40 is a support with a first end comprising a first right angle and a first angular support hole. Angular support 40 further comprises a second end comprising a second right angle and a second angular support hole.
- a user places angular support 40 between third pedestal 10 C and first pedestal 10 A by placing the first angular support hole over third pedestal first unthreaded rod 20 A 3 .
- a user then places the second angular support hole over first pedestal third unthreaded rod 20 C 1 .
- Each pedestal 10 has two stringers 30 that terminate at the pedestal 10 and one stringer 30 which passing through two threaded rods 18 separated by a diagonal distance.
- This geometry has many advantages over the prior art, and particularly Irish and its progeny.
- Embodiments of the present invention can be used as a blast floor by selecting materials particularly resistant to shattering such as metal.
- the present construction allows for even point loading to be dispersed across multiple pedestals 10 . In addition to strength it also promotes the stage floor acting as a continuous membrane in flexion instead of simply connected discrete squares as in Irish. This greatly improves blast response to irregular loading found in blasting.
- the floor in Roen may lift and deflect under severe blast loading, but embodiments of the present invention will resist the floor coming apart, and thus causing potentially lethal missile hazards.
- the floor grid also works to prevent “noticeable deflection” which the present application defines as a deflection of more than one inch per 100 feet.
- a user places deck plate 50 onto first stringer 30 A, second stringer 30 B, third stringer 30 C and fourth stringer 30 D to create a level surface.
- Deck plate 50 is shown here with a somewhat octagonal shape that contains a lowered portion proximate each corner to enable access to pedestal 10 . There are perforations in each lower portion that can permit partial access to threaded rods 18 and rotation nut 22 .
- Angular support 40 is immediately adjacent to unthreaded pedestal rod 20 and unthreaded cover rod unthreaded cover rod 68 .
- a user can adjust the height of any pedestal plate 12 by adjusting the corresponding rotation nut 22 to ensure that deck plate 50 is level, even if the ground is not level, for instance, if the stage floor assembly is assembled outdoors upon a lawn.
- the interconnected nature of the grid network will promote continuity of the stage floor assembly tending to smooth out local differences in the grade elevation from one pedestal 10 to another. This helps avoid ridges or kinks on the surface of the stage floor assembly. This is in direct contrast to Hubbard, which teaches loading about a central point, as opposed to dispersed loading at a plurality of pedestals 10 .
- FIG. 12 shows the final stage of assembly around third pedestal 10 C.
- first deck plate 50 A is placed on top of third stringer 30 C and fourth stringer 30 D.
- First deck plate 50 A is immediately adjacent to second deck plate 50 B and fourth deck plate 50 D.
- Second deck plate 50 B is further immediately adjacent to third deck plate 50 C.
- Third deck plate 50 C is further immediately adjacent to fourth deck plate 50 D.
- First deck plate 50 A is perforated with first deck plate hole 52 A which permits first unthreaded cover rod 68 A to travel through first deck plate 50 A into angular support 40 in place.
- second deck plate 50 B is perforated with second deck plate hole 52 B which permits second unthreaded cover rod 68 B to travel through second deck plate 50 B.
- third deck plate 50 C is perforated with third deck plate hole 52 C which permits third unthreaded cover rod 68 C to travel through third deck plate 50 C.
- Fourth deck plate 50 D is perforated with fourth deck plate hole 52 D which permits third unthreaded cover rod 68 D to travel through fourth deck plate 50 D.
